Photosynthesis
Green plants are producers. This means that they can survive without
animals! They can make lots of organic chemicals from a few simple
inorganic chemicals. They need simple things like carbon dioxide and
water and can make complex things like sugar, starch, fat, and
proteins.
Plants get their nutrients from the environment. Carbon dioxide comes
from the air (unless they are aquatic plants, in which case they get
it from the water surrounding them). They get water from the soil.
They also need other inorganic nutrients like nitrate, sulphate and
phosphate. A few plants cannot get nitrate out of the soil so they
have to eat animals to get the nitrogen which they must have for
growth.
Animals are consumers; they cannot carry out photosynthesis. This
means that they have to eat other things to get the carbohydrates,
fats, proteins, vitamins and minerals which they need.
When plants are in the sunlight they can make a sugar called glucose.
This is slightly different from the sugar (sucrose) which you put into
your tea. Glucose contains three chemical elements:
* Carbon
* Hydrogen
* Oxygen
All the carbon needed for photosynthesis comes from carbon dioxide.
All the hydrogen comes from water.
When plants use carbon dioxide and water to make glucose there is a
lot of oxygen left over. Here is a word equation:

Carbon dioxide and water are inorganic chemicals, whereas glucose is
an organic chemical. Plants need energy to convert carbon dioxide and
water into glucose; this energy comes from sunlight. Plants can...

they are going to grow properly.
Nitrate, sulphate, phosphate and magnesium are called mineral salts.
Here is a summary of the most important information on photosynthesis:
Photosynthesis requires:
* carbon dioxide,
* water,
* light energy,
* chlorophyll.
Photosynthesis produces:
* glucose,
* waste oxygen.
Photosynthesis is the conversion of:
* light energy into,
* chemical energy.
Photosynthesis is essential for:
* growth.
Photosynthesis takes place in:
* leaves !!!!!
Photosynthesisis the conversion of carbon dioxide and water into a
sugar called glucose using sunlight energy. Oxygen is produced as a
waste product.
Chlorophyllis the green chemical needed by plants for this process.

- Explains how light energy is trapped by a green chemical called chlorophyll and converted into chemical energy in photosynthesis. when animals and plants respire, glucose can be converted to other forms of energy.
- Explains that plants cannot store up lots of glucose, so they convert the extra glucose into starch, which can be stored in leaves or other parts of the plant.
- Explains that photosynthesis results in an increase in biomass; there is more carbohydrate in the plant; they can turn some of the glucose into fat or protein.
- Explains that fats contain three elements: carbon, hydrogen, oxygen and nitrogen. plants cannot make protein from pure carbohydrate because proteins contain nitrogen and sulphur.
- Explains that plants need phosphate from the soil to make their dna. chlorophyll contains five elements: carbon, hydrogen, oxygen, nitrogen, and magnesium.

- Photosynthesis Essaycomparative essayConclusion and Evaluation Conclusion- The data supports my hypothesis. By looking at the graph titled “Average Rate of Photosynthesis” we see massive photosynthetic activity occurring from :30 to 10:00 with particularly impressive growth occurring in red and blue light around the 5:00 and 8:30 respectively. The colors that have the highest influence on photosynthesis is blue and red. This is also why so many gardeners both amateur and professional alike use blue and red lights to grown plants.

One area of research is directed at the effects that chlorophyll may have on cancer cells within the human body. Research is being conducted to investigate whether chlorophyll has important cancer fighting factors that may play a role in the destruction of cancer cells or whether it is an effective preventive agent. Intensive research for naturally occurring plant products which reduce genotoxic effects are driven by the increasing exposure of humans to environmental toxins (Sarkar, 1994).

1252 wordsRead More - Photosynthesis Essayexplanatory essayThe process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.
